  • Solar inverter SMA Sunny Island 4.4M

Solar inverter SMA Sunny Island 4.4M

21% IVA incluido

Single-phase photovoltaic inverter for isolated installation, with solar batteries, SMA of 4400W AC, with 95.5% efficiency and maximum input current in AC of 50A

The Sunny Island inverters allow a multitude of combinations to adapt to specific needs, requiring very low self-consumption of operation with IP54 protection

The 4.4M model integrates assigned voltages in ranges from 172.5 V to 264.5 V, being able to work with a maximum CA to optimize the self-consumption, in network operation, up to 14.5 A, with a maximum power of 3.3kVA

As a backup system, it can work at 3300W in AC with a rated current of 14.5A and at 4400W for 30 minutes

The Sunny Island offers a 2-year product warranty and is CE certified


The Sunny Island incorporates a solar battery connection with a 48 V configuration and manages both charges and discharges of up to 75 A. It allows the interconnection of lithium-ion batteries as well as solar lead acid batteries.
